WATER-GATE.

SPECIFICATION forming part of Letters Patent No. 496,239, dated April25, 1893. Application tiled January 18, 1893. Serial No. 458,765. (Nomodel.)

To all whom t may concern/.-

Be it known that I, CHRISTOPHER H. WAT- SON, of Riverside, in the countyof San Bernardino and State of California, have invented a new andImproved Water-Gate, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved water gate,which is simple and durable in construction,.easily manipulated foropening and closing the same, and arranged to prevent all leakage, byfirmly seating and locking' the gate over the open- 1ng.

The invention consists of a gate mounted to slide, and a gate stemcarrying the gate and adapted to be turned, and pressed on by a spring.

The invention also consists of certain parts and details, andcombinations of the same, as will be hereinafter described and thenpointed out in the claims.l

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is aface View of the improvement with part broken out. Fig. 2is a transverse section of the same on the line 22 of Fig. l.

Fig. 3 is alike view of the same on the line 3 3 of Fig. 1. Fig. 4 is asimilar View of the same in a dierent position; and Fig. 5 is a4sectional plan view of the same on the line 5 5 of Fig. l.

The improved water gate is provided with the gate plate A having theusual opening A connecting with the pipe or flume on which the gate isapplied. The plate A is secured in the usual manner to the end B of thepipe or flume and on the front face of the said plate is adapted to beseated the gasket C made of rubber or other suitable material and heldon the inner face of the gate proper I) mounted to slide vertically insuitable guide- Ways A2 forming part of theplate A. When the gate D isin a lowermost position it is adapted to be pressed longitudinally, sothatthe gasket C seats itself Iirmly ,on the plate A, whereby theopening A in the gate plate A is closed, and al1 leakage is prevented..On the inner face of the gate D and near the upper end of the same aresecuredlugsE adapted to fit in recesses A3 formed on the front face ofthe gate plate A. A like'set of lugs E is arranged on the lower end ofthe gate D and is adapted to engage corresponding recesses A4 alsoformed on the plate Abut out of vertical alignment with the otherrecesses A3, so that in pulling the gate D upward, the lugs E do notengage the recesses A3.

In order to impart a vertical sliding movement to the gate D, I hang thesame on a gate stem G formed at its lower end with a reduced part Gmounted to turn in suitable bearings F formed or projecting from thefront face of the gate D. On this reduced portion G of the stem G issecured a cam H adapted to be pressed on by a spring I preferably madeof a pieceof iiat steel and extending transversely across the gate D, toengage with its bentends I', the outer ends of the guideways A2, asplainly shown in the drawings, especially wlth reference to Fig. 5.

In order to hold the spring I in the proper position on the gate D andto permit a compression of the same, I provide guldeways J secured onthe `gate D and through which passes loosely the said spring I. Inorderl to hold the cam H in contact at all times wlth the spring I, Iprovide the said cam with arms H extending alongl the top and bottomedge of the spring I and connected'with each other at their outer endsby' a pin H2 adapted to engage the outer face of the spring I. The bentends I of the spring I are adapted to engage wedges A5 formed on theguideways A2 opposite the center of the opening A, so

that when the gate D is in a closed position,

as illustrated in Figs. l, 2and 3, the saidl ends I engage the wedges A5to hold the spring I taut. Now, when the stem G is turned, the cam Hswings outward and presses against the inner side of the spring I, sothat the force of the latter exerts a pressure on the gate D so as tosecurely press the same with its gasket C onto the face of the gateplate A over the opening A. It is understood that this movement of thegate D can readily take place as the pins or lugs E and E now move inthe recesses Aa and A4. The upper end of the stem G is loosely guided ina keeper K secured to a transverse beam L forming part IOO of the iiurneor gate-way and the said stem is also engaged loosely by a leverNforconveniently turning the said stem to impart a swinging motion to thecam H to engage the latter with the spring as above described, so as tofirmly seat the gate D on the plate A. lVhen the cam II is swungoutward, as illustratcd in Fig. 5, then the lever N extendslongitudinally and is adapted to be locked on a staple O projecting fromthe keeper K and adapted to engage an aperture in the said lever. Thestem G is preferably made square and passes through a correspondingaperture in the lever N so that the gate can be raised and loweredwithout moving thelever N away from 'the top of the keeper K. Thedownward sliding motion of the gate D is limited by a stop P projectingfrom the plate A and the upward movement of the gate is-limited by stoppins Q secured on the guideways A2 and adapted to be engaged by the bentends I of the spring I, thus forming a stop for the gate D. It isunderstood that when the cam II is swung transversely, the spring Iengaging the pin H2 moves the gate D otl the plate A sufiiciently forthe inner ends of the lugs E and E to be clear of the front face of theplate A. Now, by raising the stem Gin any suitable manner the gate.Dslides upward to free the opening A. It will be seen that the gate Dwhen pulled upward can be locked in any desired position by turning thestem G by the lever N or otherwise, so that the cam H swings outward andpresses on the spring I. New, it will be seen that the gate D is pressedinward toward the plate A, but the gasket C is not moved in contact withthe face ot the plate, but the lugs E and E receive the contactpressure. By this arrangement the gasket is not injured in any mannerwhile the gate is partly or Wholly open, and the gasket is only usedwhen the gate is entirely closed at the time the lugs E and E registerwith their corresponding recesses A3 and A4.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. A water gate, comprising a gate mounted toslide vertically and adapted to be moved longitudinally, a gate stemcarrying the gate, the said stem being adapted to be turned, a cam heldon the said stem, and a spring adapted to be engaged by the said canifor pressing the said gate to :its seat, substantially as shown anddescribed.

2. A water gate, comprising a gate lplate having recesses and providedwith guideways, a gate mounted to slide in the said guideways, andprovided with lugs adapted to en gage the said recesses, and means,substantially as described, for pressing the said gate longitudinally toseat the same over the openingof the gate at the time the said lugsengage the said recesses, substantially as shown and described.

3. A water gate, comprising a gate plate having recesses and guideways,agate having a gasket and mounted to slide on the said gate plate, lugsprojecting from the said gate and adapted to engage the said recessesand the face of the gate plate, a gate stem carrying the said gate andmounted to turn, a cam held on the said stem, and a spring engaged bythe said cani, and held on the said gate and engaging the saidguideways, substantially as shown and described.

4. A water gate, comprising a gate plate having recesses and gnideways,a gate having a gasket and mounted to slide on the said gate plate, lugsprojecting from the said gate and adapted to engage the said recessesand the face of the gate plate, a gate stem carrying the said gate andmounted to turn, a cam held on lthe said stem, a spring engaged by thesaid cam, and held on the gate and engagin g the said guideways, andwedges formed on the said guideways and adapted to be engaged by thebent ends ot the said spring, substantially as shown and described.

5. A Water gate, comprising a gate plate having recesses and guideways,a gate having a gasket and mounted to slide on the said gate plate, lugsprojecting from the said gate and adapted to engage the said recessesand the face of the gate plate, a gate stem carrying the said gate andmounted to turn, a cam held on the said stem, a spring engaged by thesaidcam and held on the said gate and engaging the said guideways, and apin supported from the said cam and engaging the spring on the sideopposite the cani, substantially as shown and described.
